Application filed April 23, 1908. Serial No. 428,752.

To all 'whom it may concern.'

Beit known that we, ALBERT C. DANN and RALPH L. FORD, citizens of theUnited States, residing at Bell and State of Ohio, have invented certainnew and useful Improvements in Tongue- Trucks, of which the following isa specification, reference being had therein to the accompanyingdrawings.

This invention relates to tongue trucks for agricultural implements.

The object of the same is to provide a tongue truck which will exert anatural draft upon the implement, such as will neither tend to elevatethe end of the stub tongue, by means of which the truck is connected tothe implement, and thus throw the weight of the truck upon the draftanimals, nor tend to depress the end of the stub tongue and causeunnecessary friction between the ground wheels and the ground; toprovide such a truck which will accommodate itself to irregularities inthe surface of the ground without exerting a strain on the stub tongueor causing the implement to tilt or turn; whichlwill be provided withmeans for connecting a tongue thereto, which means will be adjustable tosupport said tongue either in position for use with a four horse eveneror in position for use with a three horse evener and will, at all times,support said tongue in a substantially horizontal position; and further,to provideV such a tongue truck which will be strong and durable, simplein its construction and capable of being manufactured at a low cost.

With these objects in view our invention consists in certain novelfeatures of construction and in certain parts and combinationshereinafter to be described, and then more particularly pointed out inthe claims.

In the accompanying drawings, Figure l is a top plan view of ourinvention applied to a disk harrow of ordinary construction; Fig. 2 is afront elevation of the truck; and Fig. 3 is a longitudinal, sectionalview, taken vertically of the truck. l

In these drawings, we have illustrated the preferred form of ourinvention and have shown the same in connection with a disk harrow 1, ofOrdinar r construction, which is provided with the usual stub tongue 2,tothe outer end of which is connected the tongue truck. The truck itselfpreferably consists of an axle 3 having mounted thereon ground evue, inthe county of HuronV Wheels 4 and a frame or standard 5 having its lowerend connected to said axle 3. This frame or standard may be of anysuitable construction andlmay be connected to the axle in any suitablemanner, but, in the present instance, I have shown the standard ascomprising a verticalbar having its upper end bent at substantiallyright angles thereto, as shown at 6, and extending substantiallyparallel with the axle .3. The lower end ,of the standard 5 ispreferably pivotally connected to the axle in order to allow the axle tomove about its horizontal pivot and thereby permit the wheels toaccommodate themselves to irregularities in the surface of the ground.This pivotal connection may be formed in any desired manner, but weprefer to provide the axle with a casing 7 having its central portionslightly raised, as shown at 8, and provided with a suitable bearingblock 9, which, in the present instance, is in the form of a diskarranged longitudinally of the axle and having the greater portion ofits diameter extending above the casing 7 of the axle 3. The lower endof the standard 5 is provided with a suitable bearing adapted to enegage the bearing block 9, and, in the present instance, comprisingsubstantially circular bearing plates 10 of a diameter substantiallyequal to the diameter of the bearing block 9, adapted to engage theopposite sides thereof and secured thereto by a bolt 11 extendingthrough the central portion of said plates and said bearin block, thusforming a pivotal connection between the plates and the bearing blockwhich will permit of a free rotary movement of the plates relatively tothe block and hold the same against movement in all other directionsrelatively thereto. The rotary movement of the bearin plates 10relatively to the bearing block is llmitedby a suitable stop whichpreferably consists of inwardly extending flanges l2 ,formed on theupper portion of the plates 10 and extending downwardly along thecircumference thereof to points sufliciently above the axle casing 7 toallow the axle the desired amount of pivotal movement. In addition toforming a stop to limit the movement of the axle relatively to thebearing and the standard 5, to which said bearing is secured,rtheflanges 12 serve to close the upper part of the bearing and prevent theentrance of dirt thereto. l

The bearing plates 10 are preferably secured to the standard 5 byproviding the same with llO upwardly extending grooved arms or necks 13adapted to engage the opposite sides of the standard 5 and to be securedthereto by suitable bolts le extending through the said upwardlyextending portions and through the standard. rihe stub tongue 2 of theharrow is secured to the standard at a point above i the bearing platesl() and is preferably pivot l preferably formed in two parts, as shown,to enable a cotter pin 26 to be inserted in the bent-over portion 6between the two portions of the bearing to hold the same againstmovement longitudinally of said bent-over portion. lilith this tongueplate connected to the standard in the manner shown in Fig. l, i. e.,with the tongue plate ally connected thereto to enable the truck toproper in substantial alinement with the be turned about a vertical axisto guide the stub tongue, the tongue is in position to implement.accommodate the same to either a two or a In the preferred form of thedevice, the four horse draft evener. By reversing the forward end of thestub tongue 2 is rigidly position of the bearing 25 on the bent-oversecured to a tongue plate 15, which, in turn, l portion 6 of thestandard, the bearing plate is pivotally connected to the standard 5 byproper 23 will be supported at one side of means of a bearing sleeve l5carried by tl e and some distance from the stub tongue 2, forwardportion thereof and journaled upon thus accommodating the same for usewith the standard 5, which, in the present ina three horse draft evener.stance, is circular in cross section. From the foregoing description itwill be A suitable draft hitch is coupled to the apparent that we haveprovided a tongue standard 5 at a point near its point of conl truck ofsuch a construction that the draft nection with said stub tongue. Ashere will be exerted upon the implement in a shown, this draft hitchcomprises a vertidirect line, thereby avoiding any tendency callyarranged and forwardly extending 1 to either lift the end ofthe stubtongue, and, plate 17 having at its upper and lower edges consequently,the truck to which it is sesuitable collars 18 adapted to extend about lcured, thus exerting an unnecessary pull the standard 5 above and belowthe collar i6 I of the stub-tongue-connecting means and to i be rigidlysecured to said standard by means l of bolts i9. The forward edge of theplate l l17 is provided with a vertically arranged l, series ofapertures 20 adapted to receive a bolt 2l by means of which a clevis 22is seupon the necks of the draft animals, or to exert a downwardpressure upon the truck on the end of the stub tongue and truck, therebycausing an unnecessary amount of friction between the wheels of thetruck and the ground g that the truck, by reason ofthe pivotalconnection of the axle to the standard, is capable of accommodatingsupport the draft evener. The draft hitch itself to any irregularitiesin the surface of being rigidly secured to the standard 5 and the groundwithout affecting the position the stub tongue 2 being pivotallyconnected of the standard or implement` connected thereto, it will beapparent that the standthereto. This pivotal movement being a ard andthe axle which is connected thereto limited one about a horizontal axisand the and held against rotary movement about a l axle having no rotarymovement relatively vertical axis relatively thereto, can be moved l tothe standard, it will be apparent that` the by the operation of saiddraft hitch to guide truck is, at all times, under control through theimplement in the desired direction, the the medium of the draft hitchwhich is y rigidly secured to the standard. Further,

movement of the standard relatively to the stub tongue being limited bysuitable stops i it will be apparent that, by means of the reversibletongue plate detachably secured 27 formed on the opposite sides of thebearing sleeve 16 of the stub-tongue-connecting l to the bent-overportion of the standard, l the tongue can be supported in a positionmeans, These stops are so'airanged as to l for use with either a fourhorse evener or a check the rotary movement of the truck before the samehas been turned far enough three horse evener and that, when supportedto bring the eveners into contact with the l in either position, itrwill extend in a sub implement. Suitable means are also pro- 1stantially horizontal plane from its point vided for connecting a tongueto the standof connection to the standard to the neckard 5 at a pointabove the draft hitch in yoke carried by the draft animals; and such amanner that said tongue may be I further, that the construction of thetruck adjusted to accommodate the saine for use is of a strong, durablenature, its parts few 3 in number and not such as are liable to bewitheither a three horse or a four horse evener. ln the preferred form ofthe device, come dissarraiiged or inoperative, and, consequently, theoperation of the device is this means comprises a reversible tongueplate 23 extending longitudinally to and simple and the cost ofproduction is low.
